as the halls of the kingdom are emptying, the brothers vanish.
People always makes there assertions on the forum, but I see no evidence for it. Kingdom Halls are pretty full. There are a few more JWs who stay home and watch on Zoom after the pandemic, mainly older ones, but overall attendance is, if anything, slightly up.
The churches, on the other hand, are emptying fast; of this I also have firsthand knowledge across a broad spectrum, including Catholic, Church of Scotland, Free Church, Methodist, Unitarian, Christadelphian, Brethren, and Christian Scientist churches.
